The shaving head carries semi-cylindrical first and second outer cutters disposed on its opposite width ends, and a semi-cylindrical finishing cutter and a slit cutter interposed between the first and second outer cutters. The finishing cutter has a finishing foil which is deeply curved than a foil of the first and second outer cutters into an arcuate contour having a width less than that of the first and second outer cutters. The finishing foil disposed behind the first outer cutter comes into contact with a users skin to make closer shaving than the first and second cutters. A skin guard project between the first outer cutter and the finishing cutter to protect the skin from being pressed excessively to a side of the finishing foil when moving the shaving head across a user'"'"' skin with the first outer cutter leading in a moving direction, thereby reducing skin irritation.
